Abstract

Multiple input ternary signal multiplexing circuit comprising an input stage (100, 200, ... n00) for each of a plurality of ternary input signals with an input end (10, 20, ... n 0) and an output end, and a common ternary output stage (17) connected to the output end of each input stage. Each input stage is connected to a ternary signal at the input end and has separate signal paths for the positive polarity (104, 108) and negative polarity (106, 110) components of the ternary signal which includes parallel transistor-diode combinations providing a high impedance block in each of the separate signal paths between the ternary input of the input stage and the output of the other input stages.
